Definitions

  • the present invention relates to the technical field of wind turbines and in particular to the field of transporting components of a wind turbine. Specifically, the present invention relates to a system and to a method for handling a nacelle of a wind turbine for instance for the purpose of transporting the nacelle to or from a site of installation of the wind turbine.
  • a large crane is needed to move and lift each nacelle to a vehicle to further transport each nacelle to the site for erection of the wind turbines or to transport each nacelle to a ship or a train for further transportation or just to store the nacelle before a further transportation is possible.
  • a large crane used both for loading or unloading a nacelle to or from a vehicle for transportation is typically very expensive and slow when many nacelles are to be shipped.
  • the crane is only a fixed portal crane there may be not enough space available below the crane for all the nacelles to be stored and to be shipped.
  • WO 2010/066255 A1 discloses with Figure 7 in connection with Figure 5a transport system 1 for a heavy element such as a wind turbine nacelle (see page 8, lines 14-15).
  • the transport system I comprises a frame structure 15 having four projecting parts 19. The projecting parts 19 are used for interconnecting the frame structure 15 in between a 1 St transport wheel unit 4 and a 2nd transport wheel unit 5 (see Figure 3 ).
  • On top of the frame structure 15 there is provided a cylindrical flange 16 which represents a connection means for a not depicted nacelle.
  • the connection means 16 is formed in such a manner that a tower connection of the nacelle can be attached to the connection means 16 (see page 10, lines 9-14).
  • the transport system 1 further comprises four legs 17 each being provided with two engagement openings (see Fig. 7 ). The four legs 17 can be attached to the frame structure 15 either directly (see page 12, line 34) or indirectly via extension means (see page 13, lines 15-18).
  • US 3289868 A discloses to load or unload a container to or from a truck by a system comprising hydraulic displaceable legs, which are attached to the container in a demountable manner.
  • WO 2008/000268 A1 discloses a handling system for a nacelle of a wind turbine in connection with self-loading or self-unloading of the nacelle to or from a vehicle.
  • the handling system comprises two or more lifting means for displacing the nacelle substantially in a vertical direction during self-loading or self-unloading of a nacelle.
  • the lifting means comprises displacing means with displaceable legs.
  • US 2,820,644 discloses an engine trailer comprising a frame having closely spaced side rails.
  • the frame is supported by rear wheel assemblies and front wheel assemblies.
  • the front wheel assemblies are connected to the frame through an axle and interconnected by a steering mechanism.
  • a further axle engages the rear wheel assemblies.
  • All of the wheel assemblies are of the caster type which can be swiveled relative to their axles.
  • roller assemblies which carry arcuate engine supporting ring members which are adapted for an attachment to a jet engine being transported by the engine trailer.
  • US 4,400,133 discloses a vehicle for transporting a ship screw.
  • the vehicle comprises a base structure forming a platform of the vehicle. When the vehicle is at rest the base structure can be secured to ground by means of four ram lifts, one ram lift being arranged at respectively one corner of the base structure.
  • On the top side of the base structure there are formed two supporting devices each consisting of a main cylinder-ram lift, a shelf representing a beam and a pair of plates being formed in such a manner that the axis of a ship screw can be accommodated.
  • WO 2004/101313 A1 discloses a transportation system for a component of a wind turbine.
  • the component may be e.g. a nacelle.
  • the transportation system comprises a truck which is pulling two spatially separated trailers each comprising a plurality of wheel axles.
  • Each trailer carries a trailer lift frame.
  • one trailer lift frame is coupled to one end of the wind turbine component and the other trailer lift frame is coupled to the other end of the wind turbine component.
  • the wind turbine component is suspended between the two trailer lift frames and hovers over ground.
  • a system for handling a nacelle of a wind turbine in particular for handling a nacelle of a wind turbine for the purpose of transporting the nacelle
  • the described handling system comprises a first supporting device and a second supporting device, wherein each supporting device comprises (a) a crossbeam extending between a left end section of the crossbeam and a right end section of the crossbeam, the crossbeam being adapted for supporting the nacelle in between the left end section and the right end section, (b) a left pedestal being attached to the left end section in a detachable manner, and (c) a right pedestal being attached to the right end section in a detachable manner.
  • the described nacelle handling system is based on the idea that the pedestals can be demounted from the respective crossbeam if they are not needed for keeping the respective crossbeam in an elevation above ground, which elevation depends on the vertical extension of the pedestals when being vertically oriented.
  • a demounting of the pedestal may be done for instance after the two crossbeams together with the supported nacelle are situated on a loading platform of a transportation device such as for instance a truck or a coach or locomotive cart.
  • Each supporting device may be for instance a supporting trestle.
  • the supporting trestle may comprise a mechanical stability, which allows for carrying, together with at least one further supporting trestle, the nacelle.
  • Each crossbeam may be any mechanically stable element, which, when the nacelle is supported, extends at least from the left side to the right side of the nacelle.
  • Each pedestal may be any construction, which allows for keeping the crossbeam at a certain elevation above ground.
  • the pedestal may be a leg or a bearing block.
  • the nacelle can be by placed on two or more supporting devices for instance by using a crane.
  • the respective two pedestals of each supporting device which are attached to the crossbeam in a demountable manner, can be removed or demounted from the crossbeam if they are not needed in particular when they are bulky and/or make the whole arrangement comprising (a) the nacelle, (b) the at least two crossbeams and (c) the pedestals attached to the respective crossbeam unwieldy.
  • the loading platform in particular of a truck or trailer is positioned beneath the two crossbeams of the supporting devices. Then, the loading platform of the truck or trailer may be raised at least a little such that both the nacelle and the supporting devices are lifted.
  • the raising of the loading platform of the truck or trailer may be done by hydraulics, by pneumatics, mechanically, electrically and/or by any kind of actuator installed on the truck or trailer.
  • the pedestals of each supporting device may be finally demounted before the nacelle is driven away by the truck or trailer.
  • the pedestals may be mounted again just before unloading the nacelle from the truck or trailer.
  • the unloading is then done by lowering the loading platform of the truck or trailer at least a little and then driving away the truck or trailer empty i.e. without having the nacelle loaded any more.
  • the nacelle is only to be moved locally e.g. within a working and/or a storing area it may not be necessary to demount the pedestals of the supporting devices before moving the nacelle.
  • the nacelle may be placed on the supporting devices each being equipped with demountable pedestals or legs for moving, transportation or storing of the nacelle. This may make the moving, the transportation and/or the storing of the nacelle of a wind turbine very flexible and cheap.
  • the supporting devices can be used in connection with many kinds of different types of nacelles without an adaption, as the nacelle is just resting on top of the crossbeams of the supporting devices.
  • the crossbeam is adapted to indirectly support the nacelle. This may provide the advantage that the nacelle does not come into direct mechanical contact with the crossbeam. An unwanted damage of the nacelle housing such as for instance a scratching of the outer surface of the nacelle housing may be avoided.
  • the crossbeam is adapted to support an attachment arrangement, which is constructed in such a manner that for transporting and/or storing the nacelle the nacelle can be attached to the attachment arrangement in a detachable manner.
  • the attachment arrangement may have the general shape of a plate, a frame or a bed.
  • the attachment arrangement may be mounted to the bottom of the nacelle.
  • the attachment arrangement When supporting the nacelle with the at least two supporting devices the attachment arrangement may rest on top of the crossbeams of the respective supporting devices. Thereby, the attachment arrangement may ensure that the nacelle is safely placed on the crossbeams and that the surface of the nacelle does not get any scratches as the nacelle is normally painted.
  • the nacelle may be mounted to the attachment arrangement in a slightly angular manner. This may provide the advantage that, if the nacelle has substantially an outer shape being at least approximately similar to a truncated cone (i.e. the diameter of the nacelle at a rear end is smaller than the diameter of the nacelle at a front end), the overall height of an assembly comprising the supporting devices, the attachment arrangement and the nacelle may be reduced. As a consequence, when transporting the nacelle there can be used also tunnels, underbridges and/or underground crossings, which have a limited height.
  • the left pedestal and/or the right pedestal is capable of being adapted with respect to the vertical extension of the respective pedestal. This may provide the advantage that the height for supporting the nacelle can be adjusted in an appropriate way in order to ensure a convenient further nacelle handling. Furthermore, if the left pedestal and the right pedestal have a different length with respect to each other, the nacelle can be securely supported even on an uneven and/or on a bumpy ground.
  • a pedestal may be adjusted by inserting an extension piece into or by removing an extension piece from the pedestal.
  • the pedestal may be equipped with vertical or at least partially vertical legs, which are automatically displaceable for instance by using hydraulics.
  • the elevation of the supported nacelle can be varied even if actually the nacelle is situated on the two crossbeams. In this way it is also possible to lower the nacelle down to the ground on a working place and/or a storing place.
  • the supporting devices can be provided with a set of different pedestals, wherein at least some of the pedestals have a different length.
  • the detachable respectively demountable pedestals are produced in sets of different lengths to ensure that the length of the pedestals fit to the height of the loading platform of the specific transportation device that is used.
  • each supporting device comprises (a) at least one left engagement opening being formed on a left side of the supporting device and (b) at least one right engagement opening being formed on a right side of the supporting device.
  • each side of the supporting device there are provided at least two engagement openings, which are appropriately spaced apart from each other. Then, for instance a conventional forklift can be used for correctly placing the supporting device.
  • the two or more supporting devices may be placed directly on a transportation device by employing one or more forklift trucks before the nacelle is placed on the supporting devices.
  • each fork may be driven through a separate rectangular hole in a bottom beam of each pedestal of each supporting device.
  • the system further comprises a distance element, which extends between the first supporting device and the second supporting device and which is attached to the two supporting devices in a demountable manner.
  • a distance element which extends between the first supporting device and the second supporting device and which is attached to the two supporting devices in a demountable manner.
  • the described handling system comprises at least two distance elements, wherein one distance element is provided at a left side of the handling system and the other distance element is provided at the right side of the handling system.
  • one distance element is provided at a left side of the handling system and the other distance element is provided at the right side of the handling system.
  • left side and right side of the nacelle may refer to a longitudinal axis of the nacelle.
  • the distance elements may be attached to the pedestals of the two supporting devices. Preferably, the distance elements are attached to a bottom portion such as a bottom beam of the respective pedestal. This may provide the advantage that the leverage will be optimized such that the mechanical stability can be optimized.
  • the described handling system comprises more than two supporting devices, there may be provided an appropriate number of distance elements, which mechanically connect also the further supporting device(s) with at least one of the first and the second supporting device.
  • the length of the distance element(s) may be adjustable. Thereby, the longitudinal dimension of the whole handling system may be adjusted properly to the dimension of the nacelle which is supposed to be supported.
  • the length of the crossbeam is adjustable. This may provide the advantage that the supporting devices can be optimally fit (a) to the width of the loading platform of the specific transportation device which is used (for instance a truck or a trailer) and/or (b) to the width of a specific nacelle type.
  • the length adjustability of the crossbeam may be realized for instance by inserting one or more appropriate extension piece(s) into or by removing one or more extension piece(s) from the crossbeam. Further, the lengths of the crossbeam may be provided with an appropriate automatic extension mechanism such as for instance a telescopic mechanism.
  • the system further comprises at least one guide element, which is provided at the crossbeam and which is adapted for ensuring that when placing the nacelle onto the crossbeam the nacelle is placed in a proper horizontal position.
  • the at least one guide element may be used for guiding the placement of the nacelle in the forward and/or the sideways direction in relation to the respective supporting device.
  • the guide element is formed in such a manner that a correct placement of the nacelle with respect to a longitudinal extension of the crossbeam is ensured.
  • the guide element may be called a side guide element, because with respect to a longitudinal extension of the nacelle a lateral or a sidewise correct placement of the nacelle may be ensured.
  • the lateral position of the nacelle on the crossbeam may be fixed both with respect to the left side and with respect to the right side of the crossbeam respectively of the nacelle.
  • the guide element is formed in such a manner that a correct placement of the nacelle with respect to a direction being perpendicular to a longitudinal extension of the crossbeam is ensured.
  • the guide element may be called a front guide element or a back guide element, because with respect to a longitudinal extension of the nacelle a correct placement of the nacelle is ensured in a forward and/or in a backward direction.
  • the longitudinal position of the nacelle on the described handling system may be fixed both with respect to the front and with respect to the back direction of the nacelle.
  • the guide element comprises a slanted surface. This may provide the advantage that when lowering the nacelle onto the crossbeams the nacelle or, if applicable, the attachment arrangement may slide downward along the slanted surface into the correct lateral and/or longitudinal position.
  • two slanted guide elements are employed which cooperate with each other in such a manner that when lowering the nacelle the nacelle or, if applicable, the attachment arrangement is spatially constricted in between the two side elements. This may hold both for the above mentioned side guide elements and for the above mentioned front/back guide elements.
  • the guide elements may be made with an angle so that the distance between two cooperating guide elements is increasingly larger in the upwards direction. This means that when lowering the nacelle the nacelle or, if applicable, the attachment arrangement is incrementally constrained in between the two cooperating guide elements towards the final position on the handling system.
  • the described handling method comprises (a) bringing the nacelle to a position with respect to the handling system, wherein the two crossbeams of the system are located below the nacelle, and (b) lifting the system and/or lowering the nacelle such that the nacelle is directly or indirectly supported by the two crossbeams.
  • the provided handling method is based on the idea, that the above described handling system can be used in an effective manner in order to support the nacelle for transportation and/or for storage purposes.
  • the nacelle may be brought to the appropriate vertical position with respect to the crossbeams of the handling system for instance by using a crane. Thereby, the nacelle may be lowered by the crane until it is hanging just above the crossbeams of the at least two supporting devices.
  • the nacelle When lifting the system, wherein the crossbeams are approached from below to the nacelle or, if applicable, to the attachment arrangement, the nacelle may be moved or pushed forward so that the nacelle or, if applicable the attachment arrangement, comes into contact with at least one of the guide elements described above. Thereby, a proper positioning of the nacelle with respect to the handling system may be ensured when further lowering the nacelle and/or when further lifting the handling system. The proper positioning may be ensured with respect to a longitudinal and/or with respect to a transversal direction of the nacelle. Thereby, the direction of the nacelle may be defined by its longitudinal extension.

  • the nacelle supporting bed 150 comprises a slanted surface 152.
  • the slanted surface is formed in such a manner, that a connection element 192 of the nacelle can be temporarily but securely attached to the nacelle supporting bed 150.
  • the connection element 192 may be for instance a flange, which is permanently fixed to the housing of the nacelle 190 e.g. by means of welding. When the nacelle is in operation the flange 192 may be connected to the tower of the respective wind turbine.
  • the nacelle supporting bed 150 comprises a plurality of eyes 158, which allow for instance a row or a hook to be engaged.

  • a side guide element 521 which is provided at the crossbeam 520, is used for placing a nacelle supporting bed 550 in an appropriate horizontal position. According to the embodiment described here this is achieved by lowering the nacelle supporting bed 550, which supports a nacelle 590, onto the crossbeams 520. Thereby, a lower side edge of the nacelle supporting bed 550 slides along a slanted surface of the side guide element 521.
  • connection element which mechanically connects the nacelle 590 to the nacelle supporting bed 550, is denominated with reference numeral 592.
  • connection element is a flange 592.
  • An attachment mechanism 525 can also be seen in Figure 5 .
  • the attachment mechanism 525 connects in a detachable manner a pedestal 530 to the crossbeam 520.
  • Figure 6 shows a cross sectional side view of a nacelle supporting bed 650 being supported by two crossbeams 620.
  • both side guide elements 621 having a non depicted slanted surface and front guide elements 622.
  • the front guide elements are front stop elements. All the guide elements are used for ensuring and facilitating a proper placement of the nacelle supporting bed 650 onto the crossbeams 620.
  • the nacelle supporting bed 650 comprises a slanted surface 652, at which a flange of a nacelle can be attached. Eyes 658 can be used for handling the nacelle supporting bed 650 conveniently.
  • Figures 7a, 7b, 7c and 7d illustrate a procedure for placing a nacelle supporting bed 750 respectively a non depicted nacelle into a proper horizontal position onto two crossbeams 720, which represent respectively a part of a nacelle handling system in accordance with an embodiment of the invention.
  • Figure 7a corresponds to a first relative position between the nacelle supporting bed 750 and the crossbeams 720. In the Figure 6 this first position is indicated with a circle 1.
  • Figure 7b corresponds to a second relative position, which is indicated with a circle 2 in Figure 6 .
  • Figure 7c corresponds to a third relative position, which is indicated with a circle 3.
  • Figure 7d corresponds to a forth relative position, which is indicated with a circle 4 in Figure 6 .
  • the nacelle supporting bed 750 comprises a slanted surface 752 and eyes 758.
  • the Figures 7a, 7b, 7c and 7d respectively show two different cross sectional views.
  • the respective left figure framing shows a front end of the nacelle supporting bed 750 including the slanted surface 752 and an eye 758.
  • the left figure framings are oriented parallel to a xz-plane.
  • the respective right figure framings shows a central section of the nacelle supporting bed 750, which is placed or which is supposed to be placed onto the rear crossbeam 720.
  • the right figure framings are oriented parallel to a yz-plane. Thereby, x, y, and z define a right angled cartesian coordinate system.
  • each side guide element 721 comprises a slanted surface.
  • all guide elements 721 and 722 are used for ensuring a proper placement of the nacelle supporting bed 750 onto the crossbeams 720.
  • the nacelle supporting bed 750 is lowered by e.g. a crane so that it is hanging just above the upper side of the crossbeams 720. Then, in between the operational states shown in Figures 7b and 7c the nacelle respectively the nacelle supporting bed 750 is moved or pushed forward so that the front end of the supporting bed 750 just hits the front guides 722. Then, in between the operational state shown in the Figures 7c and 7d the nacelle respectively the nacelle supporting bed 750 is simultaneously lowered and adjusted sideways between the side guides 721 while the supporting bed 750 is still hold against the front guides 722.
  • the side guides 721 are attached on top of at least one of the two crossbeams 720.
  • One side guide 721 is attached at the left side and one side guide 721 is attached at the right side of the crossbeam 720.
  • the two side guides 721 are spaced apart in a distance depending on the width of the nacelle supporting bed 750.
  • the side guides are made with an angle respectively with a slanted surface, so that the distance between the right side guide 721 and the left side guide 721 is increasingly larger in the upwards direction.
